Question

multiple choice question
what type of microscope can be used to see the two phospholipid layers in a plasma membrane, as in this image?
○ phase contrast
○ dark-field
○ fluorescent
○ electron

Explanation:

To see the two phospholipid layers in a plasma membrane, a microscope with high resolution is needed. Phase - contrast, dark - field, and fluorescent microscopes are light microscopes with lower resolution, suitable for observing larger or stained structures. Electron microscopes (like transmission electron microscopes) have much higher resolution, allowing visualization of the fine details of the plasma membrane's phospholipid bilayer.

Answer:

D. Electron
